I tryed to install this package :
NVIDIA_nforce-1.0-0261.rh90up_2.4.20_6.athlon.rpm

this is the command I used :
# rpm -i Driver_lynux_NVIDIA_nforce_1_2004Feb21.rpm

and the returned message :
depmod: *** Unresolved symbols in /lib/modules/2.4.20-6/kernel/drivers/net/nvnet.o

then when I tryed to load the nvnet module :
# modprobe nvnet
/lib/modules/2.4.20-6/kernel/drivers/net/nvnet.o: unresolved symbol skb_over_panic_R712a47ec

Hint: You are trying to load a module without a GPL compatible license
and it has unresolved symbols. The module may be trying to access
GPLONLY symbols but the problem is more likely to be a coding or
user error. Contact the module supplier for assistance, only they
can help you.

I looked a little bite around this forum but I did not find this problem anywhere

So as in the installation guide of nvidia, I downloaded the souce "NVIDIA_nforce-1.0-0261.src.rpm"
and executed this command :
rpmbuild --rebuild NVIDIA_nforce-1.0-0261.src.rpm (by using "rpm --rebuild NVIDIA_nforce-1.0-0261.src.rpm", like in the guide, rpm tell me that the option "rebuild" does not exist)

I had one hundred of lines displayed in the terminal with 10% of error

and when I try to compile the driver with the "make" command and the source files from nvidia .... same things, a lot of lines and errors

so unfortunately I can't use my network interface

it's the first time I install and manage Linux by myself
so may be I made some thing wrong
